IMPROVED POWER-HAMMER.

TO ALL WHOM IT MAY CONCERN: v

Be it known that we, THOMAS Seorr, of Madison Mills, and Jenn Cinnamon,of Pancoastburg, both in the county of Fayette, Vand State of Ohio, haveinvented a. new and useful improvement in Foot Trip-Hammers; and we dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in theart to makeand use the same, reference being had to the accompanying drawings,forming part of this specification. I

This invention consists in an arrangement whereby a trip-hammer isoperatedby the foot with the aid of springs and a rack `and pinion, bywhich the hammer is made to traverse the anvil, and also in the deviceVfor reversing the hammer. v

Figure 1 is a side view of the whole arrangement.

Figure 2 is a front view.

Similar letters of reference indicate like parts.

A is the platform or base, to which the anvil and other parts of theapparatus are attached. B is the anvil. C represents the hammer. Thehammer-handle is attached to an arch marked D, which is attached to` asliding carriage, E. This carriage works grooved timbers, (which arerigidly attached to the platforun) marked FF. Gr is an elliptic spring,which is fastened to the carriage by a bolt, or in any other suitablemanner. ais a stand, which is rigidly attached to the-top ofthe springG. D is a sleeve on the end of the hammer-handle H. On the lower side ofthis sleeve there is an ear, e, to which the stand a is attached byapin, or in any manner which will be suiiciently substantial and formajoint thereby. Passing through the arch D there is a. clevis iconnection markedf, to which the extreme end of the hammewhan'dle isattached. On the opposite side ofthe arch there is a diskor collar onf,marked c, which has notches in its periphery, and attached to the archthere is a spring, g, which has on its under side a little ledge whichdrops into the notches on the disk and thereby holds the clevis j' inplace. The hammer-handle turns in the sleeve` d, and the hammer isreversed by ra'ling the spring g from'the disk C and turning the handlehalfway round, when the spring g drops into another notch and holds theclevis connection, and consequently the hammer, in the desired position.J is a spring, which is attached to a cross-bar, 71,011 the arch D. Asthe hammer is thrown up by the force of the elliptic spring G, thehandle strikes the end of this spring J, expending thereon the force ofthe momentum of the hammer.

The spring recoiling therefrom starts the hammer back in its downwardmovement with increased force. The 1 blow of the hammer on the anvil isproduced by the action of the foot upon the lever-treadle K. This leveris hinged to the carriage E, as seen in the drawing. It is formed of twolevers, in fact, K and K', in order to i operate upon the hammer-handleso that the hammer will strike in about the middle of the'anvil. Forthis purpose the lever is double, one portion being the treadle K, andthe other, K', being attached to the hammerhandle by the rod L, as 4seenin thc drawing. This double lever is secured to the carriage by theportion of it which is bent at right angles with the lever, and which isseen at m attached to the carriage by eyes n 71.. In order that thehammer may be made to strike upon any part of the anvil, there is a rackattached to the'front part of the carriage E, seen in fig. 2, marked O.P is a shaft, upon the end of which is apinion, O. The shaft issupported at its outer end by the anvilblock and by one of thestationary carriage-ways F at the other.` Upon the outer end is adisk-wheel, r, which has pins on its face, z', by which the shaft isrevolved, by the `hand or by the foot, while the hammer is in operation.It will thus beseen that the hammer may be madeto strike the iron uponany part of the anvil, and that it can be readily reversed, so that thepene of the hammer can be used when desired.

What we claimas new, and desire to secure by Letters Patent, is- Y 1.The combination, substantially as shown and described, of the clevis f,disk c, spring g, and sleeve d, whereby the hammer may be reversed,substantially in the manner-set forth. 2. The arrangement of the severaldevices for producing the downward and-upward stroke and the lateralimovement, substantially as herein shown and described. i
